Programatically generate custom scales

Is there a way to programatically generate custom scales? I am building a Figma plugin to add radix colors in a variable collection. Given the target audience (designers), a custom palete generator would be appreciated. At the moment I will process the output of the web page. I see that my question is a bit of topic as the npm package has only the colors, but I was thinking of an extension or another easy one is a nextJs api route added to the current web app that serves the web generator based on the same JS code... Thanks, Sorin
